Answer:

x=1

Step-by-step explanation:

Convert decimals to fractions:

11/5x + 11/5 / 4= 1.1

Simplifies the fraction:

11x+11 / 20= 1.1

Remove denominator (then multiply by 20 on both sides):

11x+11=22

Move the x to the left:

11x= -11+22 → 11x=11

Simplify:

11x=11 → x=1

Answer:

x = 1

Step-by-step explanation:

11/5x + 2.2/4 = 1.1

11/5x + 11/5/4 = 1.1

11x + 11/5/4 = 1.1

11x + 11/20 = 1.1

11x + 11 = 22

11x = 22 - 11

11x = 11

There are 32 students in a class. Of the class, 3/8 of the students bring their own lunches. How many students bring their lunch
OverLord2011 [107]

Answer:

The number of students that bring their lunches is 12        

Step-by-step explanation:

Let

x -----> the number of students that bring their lunches

y -----> the total number of students in a class

we know that

The number of students that bring their lunches divided by  the total number of students in a class must be equal to 3/8

\frac{x}{y}=\frac{3}{8}

x=\frac{3}{8}y  -----> equation A

y=32 -----> equation B

substitute the value of y in equation A and solve for x

x=\frac{3}{8}(32)

x=12

therefore

The number of students that bring their lunches is 12
